4Serial No. 87,728.l

To ill whom t may concern:

Be it known that LJOHN T. HowmsoN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements' in Recording Mechanism, of which the following is a specification.

.This application is a division of my application filed July l29l 1901, Serial No.

70,061, series of 1900, for improvement in calculating machines. That priorapplical tion discloses acombined adding and typewriting machine and claims various features which have more especially to do with the adding or registering function of the ma-y chine, and combined adding and typewrit-V ing functions. The preseiit application pertains more especially to those features which are or may be mechanically independent of the adding or registering department of the machine. Thus the present invention relates especially to control of f a laterally,4 shiftable paper carriage, as to margin setting and tabulating shift.

ln embodying the latter feature according to the present di-sclosure I provide for disabling the e'scapement mechanism which ordinarily controls propulsion of the carriage y its spring, and I bring into play tabuble and interchangeable bar whereby l greatly facilitate a change of tabulation con trol from that suited to one sort of accounting work in hand to a condition suited to another. 1

In lthe drawings which accompany and form part of this specification, Figure 1 represents a top plan view of the complete machine; Fig. 2 representsa left side elevation of samewith thev casing partly'in section and partly removed altogether along` with the left side frame` piece; Figs. 3 and el are similar side elevations of the tabulator devices together with the lcarriage and carriage-track and means for shift-ing'the lat,- ter; Fig. 5 is a top plan View on an enlarged scale of escapement mechanism; Fig. 6 is a front elevation of the same mechanism; Figs. 7 and 8 are similar plan views of part of whatappears in Fig. 5, and they illustrate different conditions in operation vertical section takensubstantially on the line 9*-'9 of Fig. 1;, Fig. 10 is afrear, elevation of` the macapitals,

chine; Fig. 11 is a detail plan view of The veg/ board and Iveymechanism- As shown more particularly in Figs. 1 and 2 of the drawings, the machine has the two side frames 11 and l2 and ,thel end lor rearV frame 13 which maybe more or less open but adapted` to support and practically inclose the working parts therewithin. The key board, here shown, is a double key board, containing in the'presentinstance eighty-three writing keys besides having additional keys such as the shift key, error key, tabulator-stop key, as well as a top row of nine carriageshift keys. Obviously the number of keys may be varied as desired but the key board herein illsutrated vis designed as capable of satisfying all comcounting from the right hand of the ma-` chine being used for cents, that is hundredths of 'a dollar, and the remaining keys for the dollars. There are consequently nine banks of keys, and two sidebanks for the shift. key, margin stop key, error key, and `two keys for eiphers for the calculating mechanism and such other characters desired. Provision is made for 0p- `erating the machine on the upper and lower case principle, as will be hereinaftermore particularly explained, and consequently each key button bears twov characters, corresponding with the type on its coperating type bar, having for upper case work all the letters of the alphabet, both smallletters and as well as other characters such as punctuation, etc., and also the figures 1 to 9 for ordinary typewriting; while for lower case work the buttons in each of the nine banks of keys bear the numbers ,1 to 9, the

inc

machine being shifted to uppercase for f ease, are comprised in the iirst row, the keys numbered 2 ybeing in the second row and soy lli) ' rc; l handtas .lll

located below the key on up to 9. n either-side the. key board, has a spacing key 14.

rlhe key board 4here shown, is preferably composed of two parallel inclined plates and 16 secured at their front end to the front strip 17 of the machine frame and at their rear. end supported on a cross rail or bar 18.l bese plates are provided with registering holescorresponding in number to the number of keys on the key board-and receiving the key stems whereby such plates 'act' as guides for these stems. llach key comprises a stemlf) with a button 20 at the upper end above thekey board and communicating` with an arm of a bell crank 21 which is board and is free to turn on a stud 212 secured on an angle piece or strip fastened on to the under side' of `the key board plate 16, there being one of such strips for each bank of keys. rlhe other arm of the bell crank is connected, in the present instance, to a horizontal wire or rod 9A extending rearwardly of the machine, in cooperative relation with certain parts of the calculating mechanism. The rear end of'each of these rods is connected to the y downwardly extending arm of its proper .dll

titi

bell crankwvhich is loosely pivoted to a rod Q6 arranged between standards 27 that rise from. an arc 28 extending between and secured to the side frames. .Each of these bell cranks, and consequently the rods and keys connected thereto, are held in nor mal position by suitable springs, such asthe coiled springs '29 secured at one endto the bell cranks. Each of the nine banks of keys has its own standard except the two end standards which accommodate ten keys, all of said. parts being arranged within small compass without interfering with the proper operation of each other. rllhe upper arm of each bell crank is connected. by means of a rod or wire 30 to its proper type bar 31, cach of which bars has a hanger secured to the arc 32 which is fastened to the two side frames 11 and 12. lilach type bar has a type block 34 having, in the present instance, two characters, which, when a key is operated, strikes'upon the top of the platen at the printing,` point so that the typewriter works on the upper and lower case principle and. also prints visibly.

Geac/ral construct/oa of carriage (mol can moge shaft.

- lllie 'carriage comprises a traine 35,with end bearlnfs 3G and 37 in which the shaft b `38 of theplaten 39 hears, one end of which shaft has the usual hand wheel or knob 40 for turning the platen by arms 41 rotatably secured inthe endl bear ings serve to'l'normally hold the platen in place, as shown clearly in Figs. 3 and 4. bviously when these arms. 4:1 are turned at an angle of ninety degrees from that there hand. Small bent` shown, the platen is `free to be removed 'by raising it bodily 'from Aits bearings. The carriage is mounted on the supportingframe l2 having end `portions l?) which are piyoted to the side frames studs or screws 44; so that the entire support?! ing frame together with the carriagev which it supports, rocks on a pivotal axis suliistanm tially atl the lowermost point of such car riaoe supporting frame. rllie carriage prefera ly has a ball-bearing,` connection with its supporting frame and to lthis end tlie'long sides oit' the arriage are ilanged or extended downward and provided on their inner faces with longitudinal ball-ways or grooves while the carriage supporting frame has at its upper ends outer ball-ways or gro y 46, saidways receiving a series of balls fl'l'.

The carriage 11 and 1Q by means of,

supporting frame is held to,-

ile

its normal rearward position by 1nica-ns of a 1 spring L18 connected `at one end to the niaciine ,frame and at the other end to a pin Li9 fastened to the carriage supporting :trarne at the rear of its pivotal porting frame has a second pin 50, which engaged by a slot 51 inethe end cfa rer-- tical arm of a bell crank 52 which is piyoted,

at 53 to one of the side frames, in the prese ent instance, to the left hand side frame. 'lhe horizoiital ,arm of this bell crank en tends forwardly underneath the -key board and is there pivoted to the shift-key which, when depressed, rocks the bell crank vand throws the carriage supporting frame and consequently the carriageto its forward or upper case position for typewriting purposes. In order to maintain said forward position of the carriage the shift key, 'which is normally rearwardly pressedv by means of a spring; 55 fastened thereto, is provided just below the button with a notch 56 so that when the lshift key is depressed the notch will engage underneath the top plate 15 of the key board, the key being by the spring,` to cause said engagement. rlhis position is maintained until the shift key is released at the will of the operator by drawingthe button forward so as to permit the spring` i8 to restore all the parts just described to normal' or lower case position. 'In the* drawings, Fig. 3 represents such non v nial position in which it is observed that the shift key is (t its normal or raised position with its notch 56 above the key board plate, while Fig. l represents the parts in shifted position, the shift key having been depressed andA held in that condition by the engage# nient of its notch with the key board plate.

The escapementmccham'sm;

The escapenient mechanism about to be described 'is' mounted upon or carried by a naain bracket 57 securedto the rear end fframe 13 substantially extending forwardly beneath the carriage point. rlhis supdrawn rearwardly i iis' centrally thereof and# meente j vas clearlyillustrated in Fig. 9, and is opforwardly, with the escapement mechanlsm, to -be de horizontal plane.

erated by a universal bail mechanism. This bail mechanism comprises a lower rod 58 extending from side to side of the machine just beneath such main bracket and is engaged by the hook-shaped end of the rearwardly extending rods or strips 59 which are connected. to and lactuated by the key mechanism hereinbefore described. For this purpose these rods or strips 59 yare pivoted to thel lower arm of their respective bell cranks 25 at the point 60 so as to be operated at every movement of such bell cranks. -A cross rod 6l may, if desired, be used for the purposepf supporting the free ends of said strips 59-and thereby relieve the universal bail of the strain of their weight. Each bell crank has its own strip 59 which consequently corresponds in number to the number of writing keys on the key board, the spacing key being also connected thereto but in a direct manner." The. depression of one of these writing keys, or of either of the spacing keys,

and by reason of its connection scribed, willcause a one space movement of the carriage just assoon as the key 1s released. The rod 58 is hung at the lower end of two brackets or hangers 62 and 63, the former being yat one of the side frames and the latter toward the center of the rod 58. Both hangers are secured to the rock shaft 64 having bearings respectively in the main bracket'57 and in the left hand side 0f the frame l2.` An arm 65 extends upwardly from this rock shaft and is connected to a rod or link 66, which, extending forwardly, is pivoted to and actuates a plate 67 which, in the present case, has 'a movement in a This plate 67 is pivoted upon the main bracket at the point 68 and a set screw l69 mounted in'said bracket is .preferably provided to serve as an adjustable stop Upon aA stud 70 screwingonto this plate is a pawl frame or bracket 7l .which is held in normal position by a spring 72 coiled around` the stud. This pawl frame has a' downwardly projecting lip or flange 73 which de; termines the normal position thereof by acting as a stop. Pawls 74 and 75 are pivoted intermediate of their lengths between up- Wardly extending parallel sides o f the pawl frame.` The pawl 74 isthe live pawl and the pawl 75 the dead pawl. `Around the pivot between these pawls is a coiled spring lftrvhose ends'` engage under the pawl inad- Vance 'of theirv pivotal points. A'- coiled spring7 7 is arranged beneaththe outer end of `the dead pawl and normally tends to force-thatend upward and the opposite'end downward." A pin or stud .7 8 projectsl laterally from'the pawl frame'in the direction of the rock'shaft l64,- and lis preferably provided i with a roller 79 vof the plate 67 and designed to afford freewill therefore pull this rod 58 cent to t for the movement of such plate.

- shifted inward toward bearing upon the top face dom of movement to such frame. To likewise permit the'plate 67 to operate freelyv and also to support its outer end, a banking roller 80 is secured to Aunderneath such plate.

The main bracket has bearings 81 for a shaft on which is secured a ratchet wheel 82 and a pinion 83, the latter being continually in mesh with the rack 84 on the under side of the carriage, as is clearly illustrated in Fig. 9. The pawls 74 and, 75 coperate with said ratchet wheel and together therewith v constitute the escapement mechanism proper for the carriage. `When a writing, numbering or spacing key is depressed, the resulting movement imparted to the universal bail shifts the plate 67 as lwell as its two pawls 74 and 7 5 lin the direction of such bail, that is, rearwardly,y thereby releasing ,the live pawl from its normal engagement with the ratchet'wheel and bringing the dead pawl into engagement with such wheel in the same space heretofore occupied by the live pawl. Upon a release of the depressedkey, the parts will assume their normal position whereby the dead pawl will be released from the ratchet wheel and the live pawl caused to enter the space in such wheel immediately the main bracket andu above that theretoforeoccupied by it, there e by permitting the ratchet wheel to move one tooth and advance th'e carriage one space.

In .order to release the pawls from engagement and permit the carriage to be shifted by hand, Athe followi-ng arrangement is provided: The main bracket has lugs 85 in whichfbears a shaft 86 hav-inonear one end an upwardly extending` arm 87 bent over at its to and also having. at its end adjalie stud 78 a downwardly extending arm 88. This stud 78 projects in the path of this arm-88 so that when thelatter is movedby the rocking of the shaft 86, the stud andconsequently the pawl frame of which it forms a part, is forcibly shifted laterally on thestud 70 as a pivot, so as to take theposition illustrated in Fig. 8. At this time both lpawls are shifted out of. engagement withl the ratchet wheel so that such wheel is-free to move in either direction, vthereby permitting the carriage to be freely moved by hand. For operating this arm 87, a releasebnil 89 is arranged beneath andlongitudinally of the carriage with its bent ends pivoted to lugs 90 on either end of the carriage and on the under side thereof. A releaselever 91 pivoted at 92 on the extension 93 of the carriage has its arm 94 extended linward above the release bail (dotted lines. Fig. l0) which is upwardly spring-held bya spring 95 (dotted lines F ig.

Obviously when this releasing lever is the carriage, which operation is performed by hand, the release fait.

bail is depressed, orroclred downward and to the carriage.

' The tabulator mechanism.

14s shown, bail ,40.0, extending parallel to` the carriage, is pivoted to the carriagesupporti-ng frame by means of studs -401 I engaging its side members and entering into 4 throw of tabulator key,

rEhe lett-hand side member .of

said trame.

402 projecting subthe bail has an extension stantially downward beyond the pivotal point and provided with a laterally extending-pinf-or stud 403 which is on the same center or axis as the center or axis .on which the carriage carrying frame oscillates, the purpose of which arrangement will be hereinafter 'made apparent. A lever 404 is pivoted at 405 on one of the side frames of the machine, in the present instance on the left-hand sideframe, and extends from the keyboard rearwardly, terminating immediately below and adjacent to said pin 403. The forward end of such lever is provided with a key 406 for convenience termed the which, when depressed, raises the rear end of the lever 404 upwardly, by whose contact with said pin the bal 400 is position indicated by the Figs. 3 and 4. The object et having this pin 403 on the same axis as the carriage carrying frame is to always insure thezsalme the bail, whether the carriage has been shifted to either upper or lower case vit position.

A strip or rack 407, which will be hereinafter termed the jumper rack, issuitably mounted onthecarriage frame, preferably in such 'manner as to be readily removable` 1n the present instance, e jumper rack are provided with slots 408 to receive studs 409 screwing into the carriage frame. rlhe left-hand slot (right-hand as the parts are viewed from the rear in i elongated and Fig. 10) is the stud 409 has extending, through it a and reversibl: both ends ot t springpressed pin 411 with itsl head overlapping and bearing against the left-hand end ci the jumper rack. rlhis construction rovidies for the ready insertion or 4removal or the reversal of the jumper rack. 'Both edges of the jumper rack have a series of holes '412 arranged at predetermined or regular intervals ,and ,screw-threaded to' 'receive studs lor stop pins 4 l ber et theaa stop pins than the number-oil 'jump for moving the carriage is twisting 1 3. ,A less numnaciente stop pins being adapted to be set or changed by the operator to different positions, thatis to diil'erentholes in the jumper rack according to the amount of required by such operator. Substantially at the center point of the length of the cross barot bail 400 which 1 shall term the margin rack and extending over the top of the jumper rack, is a substantially U-shap'ed dog 414 adapted to. .coperate :with the jumper 4rack 1in the manner hereinafter stated. l

ds clearly shown in Fig. 11 substantially one-half of the' forward edge of the margin rack is provided with'rack teeth 415 corresponding in spacing to the spaces indi! cated on the paper scale hereinafter described. To. coperate with -these racl teeth an adjustable margin stop is provided, such stop consisting, inthe present instance of a substantiallyrectangular shell 416 having one end of one side bent inward to form a tooth 417 adapted toengage the rack teeth, and with the opposite end bent laterally to form a stop 418 for a lug 35a on thecarriage to abut. One end of the other side of the shell is bent inwardly at 419 to bear against the smooth rearward side oi the margin, rack. ln order to normally keep th tooth 417 in engagement holes is used, these with the rack, suitable tension may be provided and such tension, in the present instance, is aiiorded by a leaf spring 420 adapted to bear against said margin rack and thereby'normally keep said tooth in engagement with By pressing upon the stop and slightly the shell against the tension of the spring, the tooth 417 can be released from en agement and the sh ll or margin stopV adjusted along the marginrackto any predetermined point thereon.

When the tabulator key is depressed the margin rack is thrown rearwardly and downwardly as hereinbefore described. which action swings the upper free end o the jumper dog 414 into the path of movement of the pins on thejumper rack. i-

.multaneously, the undery {side of the vbail dit 'on the margin rack contactsv particular point at which the carriage is' to be stopped can. be regulated by the operator.- Furthermoren for convenience, where the machine being employed for two diierent kinds of tabulating work the titi 'adjust his jumper rack may have the stop pins adjusted on one edge in a certain manner and the stop pins arranged on the opposite edge in a different mannerso that when the operator Wishes to machine, all that will be required is to simply reverse the position of the jumperrack. j Y I As hereinbefore stated the margin stop maybe set at any desired position on the margin rack and the carriage will stop when it abuts against the stop 418 under backward movement. Should occasion arise for typing in the margin `the bail may be 4swung rearward and the carriage moved farther back.
